BAG-HOLDER.

Specification of Letters Patent.

Patented Mar. 26, 1918.

Application filed April 23, 1917. Serial No. 163,992.

To all whom it may concern Be it known that 1, WILLIAM Jenn Anars'rnone, a subject of the King of Great Britain, residing at Brussels, in the Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Bag-Holders; and I do hereby declare the following to be a fulh clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in bag holders. lhe principal objects of the invention are to eiiect a saving of time and labor in filling bags, and to devise a simple form of holder which will hold the mouth of the bag distended and will retain the sides in an extended position throughout the operation of filling. A further and importaut object is to provide a holder which may be operated to shake the material down as the bag is being filled, the operation being substantially the same as when a bag is shaken by hand.

The principal features of the invention consist in the novel construction and ar' rangement of parts whereby the upper edge of the bag is held by a member arranged upon a sliding support and whereby supporting member is operated with a reciprocal vibratory movement, the arrangement being such that during this movement, the upper edges of the bag are brought together and separated to assure proper settling of the contents.

The drawing represents a perspective view of a bag holder constructed in accordance with my invention.

Referring to the accompanying drawing, the upright 1 is supported upon a suitable base, here shown, formed with the laterally extending legs 2 and 3, the legs 2 being preferably arranged in transverse alinement.

at is a block slidably arranged upon the upright 1 and supportedby a bar 5 which is adjustably and 'pivotally connected at its upper end to said block. The lower end of the bar 5 is pivotally connected to one end of a lever 6 which is supported interme diate of its length upon a bolt 7 secured in one of the legs 2 adjacent to the outer end. The lever 6 is provided with a foot pedal 8 at its outer extremity.

9 is a coil spring having one end secured to the lever 6 adjacent to the outer end and the other end secured to the leg of the frame so as to efiect a downward pull upon the outer end of the lever and therefore exerting a constant upward thrust upon the inner end of said lever and the bar 5 thus spring holding the block 1 in an upward position.

10 is a pin secured in the front side of the block 4 forming a pivotal support for a pair of L-shaped arms 11 which extend laterally outward from the block. The arms 11 are spring held in an extended position by means of a spring 12 which is coiled around the pin 10 having the ends 13 thereof secured to said arms adjacent to their outer ends.

The end of the bag is looped over the forwardly extending portions 14 of the arms 13 and is secured in position by pivotal locking members 15 which are of L-shape and are pivoted to the arms 13 and extend around the corners of said arms and grip the bag. The mouth of the bag is thus spread in one direction by the length of the portions 14 of the arms and in the other direction by the spread of the arms.

The spring 13 holds the arms distended but allows of a certain amount of flexibility. The bag when thus hold is supported above the floor, the block 4. being adjusted on the bar 5 according to the length of bag. As the grain or other material is placed in the bag the spring supports of the block and of the arms 13 allow the bag to assume the desired position so that the weight is entirely carried on the floor but the sides of the bag are held taut by the spring pull. The holding members 15 retain their grip until the bag is filled and released.

"While the bag is being filled it is desirable to shake it with an up and down jerking action in order to settle the contents down thoroughly and this is accomplished by placing the foot upon the pedal 8 and operating the lever 6 and rod 5 to raise and lower the same with a jerking action. It will be seen that, when the block 4 is raised by pressing the foot pedal as just described, there will first be a downward pull on the outer ends of the arms 11, due to the weight of the bag and contents, and the spring 12 is of such strength that it yields initially to this pull. The sides of the bag are thus brought together to compress the contents, in the same way that they are brought together when a bag is shaken by hand after fit being grasped by its upper edges. Subsequently to this initial movement, however, the tension of the spring will resist further downward movement of the arms, and con tinned up and movement of the block will lift the bag from the floor. When the pedal is released, the bag will strike the floor suddenly, and the spring will spread the arms separating; the sides of the bag and permitting the contents to settle properly. to be noted especially that the holding mem bers 15 are arranged to prevent disengagement of the bag from the arms when the latter are moved inwardly.

A bag holder such as described may be constructed very low cost. It is easily handled; and will not readily getout of order.

That I claim as my invention is In a bag holder, the combination with an Gopies of this patent may be obtained for It is position and to resist yieldably downward" movement of the arms, means for raising and lowering the block, and means carried by the arms for fastening a bag thereto at its edges in a way to prevent disengage ment of the bag therefrom through move ment of the arms.

In testimony whereof, I afiix my signa ture in the presence of two witnesses.
